Document Summary

Geol104 lecture 31 surface and groundwater: drainage systems are patterns of the interconnected network of streams in an area. Dendritic: develops on relatively uniform surface materials, smooth curvy branches like tree. Rectangular: develops on highly jointed bedrock, cactus shape, corners rather than curves. Radial: develops on isolated volcanic cones or domes, spreads out radially, drains from high area, out in all directions from central point. Parallel: just straight-ish streams parallel to each other, formation of a water gap. A water gap is a notch where a river cuts through a ridge that lies in its path. Two possible methods of formation: stream existed before the ridge was formed, river there first, then came folding, stream was eroded into a pre-existing structure, river erodes material away to exposed fold. Superposed stream: as the stream erodes downward, it encounters and cuts through the resistant rock units creating water gaps, headward erosion and stream piracy.
